D Major fingering

If you are playing it clean and can move to and from other chords comfortably that way just go with it. To my knowledge any one can use any fingers to form a chord as long as it is at the correct fret an on the correct strings. You might find help on some of the online sites for guitar lessons. Just remember if you use your index, middle and ring finger it will prepare you better for playing the other D chords easier.

You are never wrong to do it your way.  Lots of guitarists have their own way of strumming, picking and fingering chords.  Whatever is easier for you is the right way.

This, plus a bazillion.

That chord shape is one of the hardest things in the universe for me to get farther down the fretboard.  I think anyone that can play a closed D shape well is a complete stud.

/ cannot play a closed D shape well. 

Tony,  That's a  pretty unique way of playing D. But not a wrong way to play it. I play it with my index on the G string, middle finger on the E string and ring finger on the B string.  That gives my my little finger to add accents on the E string as needed.  However, what has been clearly pointed out here is that, "if it works for you, do it." There's always going to be a chord that one person will play differently from another person (for me it's G).  What's important is: Does it sound good? Does it fit with the Chord Progression?  There is nothing wrong with your D.  Especially if it sounds good and lets you change to other chords with ease.  Rock on! Dguyton hit the nail on the head about the barre chords too.  Any time you get to use your little finger will always add strength to your playing later on.

I've heard a lot of suggestions for not using the index finger when starting out to make barre chords easier down the road.  You might be on to something Tony. 

I found that it took quite a lot before I was able to change chords and play them clean... in fact, they still aren't always clean; sometimes I have to concentrate really hard.  Then I lose my rhythem or am concentrating so hard on playing them clean that I forget the chord progressions.  It's a matter of practice for sure.  I just found out the other day that my fingers actually know where they're going, I closed my eyes and was able to play through an entire song without staring at the neck... I had no clue I could do that.  It wasn't all clean, and I my fingers weren't staying right at the edge of the frets, but it was there.  Just keep on keeping on and you'll get it!  Practice it clean, picking out each string to see if you've got it and excatly where your fingers need to be to get it, and also practice chord changes both with attempting for speed, and again with attempting for accuracy.  I think the thing I hated most about the "beginning" was feeling like I'd never "get it" and be able to play anything that sounded decent.  My mind was ready to learn the next chord, but my "fingers" weren't.

There are five basic chord shapes.  C A G E and D.  You can play them anywhere on the neck.  When you play them "open,"  are playing them at the nut.  If you play them further down the neck, they are closed.

For example...

D major using the D shape, I'm sure you're familiar with.  This is playing an "open chord shape."

e-2
B-3
G-2
D-0
A-x
E-x

But how about F, using the D shape. Essentially, a barre chord.

e-5
B-6
G-5
D-3
A-x
E-x

Same chord shape, just moved up the neck a little.  This is a "closed D shape."

Make sense?
